Feltgen says Beaumont, Texas, and Cameron, Louisiana, are “still under the gun” for rain from Harvey, and conditions won’t improve until Wednesday night.

The storm is forecast to then move from Louisiana into northwestern Mississippi, Tennessee and Kentucky.

The National Weather Service is predicting 5 to 6 inches (13 to 15 centimeters) of rain in western Tennessee. Flood watches and warnings have been issued for parts of Louisiana, Mississippi, Arkansas and Tennessee.
